Influence of synthesis conditions on complexation of Cu (II) with O,N,O tridentate hydrazone ligand. X-ray diffraction and spectroscopic investigations
(I), [Cu(HL)Cl] (II), [Cu2(HL)2Cl2] (III) and [Cu2(L)2Py2] (IV). Complex I is interesting by the presence of two differently coordinated ligand molecules. Mononuclear complex compound II and its dimeric analogue III were obtained from the same reagents: CuCl2 and HBPAH but in different reaction conditions. In dimeric complex IV the HBPAH molecules are coordinated as dianions in imidol tautomeric form
摘要 合成了四种具有 (E)-N'-(2-羟基亚苄基)-2-苯基乙酰肼 (HBPAH, H2L) 的新型 Cu2+ 配位化合物,并通过单晶 X 射线衍射法、IR、UV-Vis 和 EPR 进行了表征。光谱学。在所有获得的化合物中,配体以典型的 O,N,O-三齿螯合方式配位。已经表明合成条件对所得复杂化合物的结构有很大影响。根据起始 Cu2+ 化合物、试剂浓度、pH 值和二级配体的存在,HBPAH 作为中性分子、单阴离子或双阴离子配位,形成四种不同的复合物:[Cu(HL)(H2L)]NO3 (I), [Cu(HL)Cl] (II)、[Cu2(HL)2Cl2] (III) 和 [Cu2(L)2Py2] (IV)。由于存在两种不同配位的配体分子,复合物 I 很有趣。单核复合物 II 及其二聚体类似物 III 从相同的试剂中获得:CuCl2 和 HBPAH,但在不同的反应条件下。在二聚复合物 IV
Design, synthesis and in vitro antimalarial activity of an acylhydrazone library
A library of acylhydrazone iron chelators was synthesized and tested for its ability to inhibit the growth of a chloroquine-resistant strain of Plasmodium falciparum. Some of these new compounds are significantly more active than desferrioxamine DFO, the iron chelator in widespread clinical use and also than the most effective chelators. (c) 2005 Elsevier Ltd.

the studied complexes were investigated using the DFT-B3LYP/GENECP level of theory. Quantum and non-quantum global reactivity descriptors as well as the nonlinear optical properties were calculated. Biological parameters such as antimicrobial and antioxidant activities, fluorescence quenching studies, and viscosity measurements of the complexes were carried out. Molecular docking studies of HL1 and
